Schneider Electric QOU2801042 Circuit Breaker

QOU2801042 is a Square D by Schneider Electric two-pole miniature circuit breaker in the QOU family, rated for 80 A at 120/240 VAC with a 10 kA interrupt rating, and designed for DIN rail mounting in compact control panels and distribution enclosures. This thermal‑magnetic breaker provides overcurrent protection for circuits fed from a 120/240 VAC supply, tripping to prevent wiring damage during overload or fault conditions. The 2‑pole design enables simultaneous disconnection of both hot conductors in a 240 VAC circuit, and the QOU designation identifies it as a DIN-rail‑style, 80‑amp, 2‑pole unit compatible with Square D QO/QOU system installations. With its 10 kA short-circuit interrupt capability, it is suited for protecting feeders and branch circuits in commercial or light industrial control applications that use DIN rail mounted protection devices.
